Added DDR3 2400 to Rampage Extreme III Need Help

[jack d]

Hi,
I have a Rampage Extreme III and am trying to get some additional life out of it by adding new RAM. The CPU is an Intel Core i7 970.

I replaced the old 12 G of ram with 24G of Corsair Vengeance DDR3 2400.
1. All ok in that the 24 G of RAM was recognized by Windows (10) but it was running at 667.4 MHz.
2. Went into BIOS and increased the DRAM Frequency to 2400. PC booted up fine and CPU-Z saw 24G of RAM but Windows only saw 6G.
3. After a bit of research on the net I realized I should enable XMP. So I did that. There was only 1 built in XMP profile (by INTEL). Booted up fast but when loading Windows I got various BSOD errors upon trying boot up a few times.
4. I read that sometimes XMP presets don't work so I should set up the profile myself. And that is where I am seeking help. I am capable enough to get into the BIOS and fiddle a bit but I don't really know what I'm doing when it comes to setting CAS latencies etc. I don't really care about OCing CPU at this point. I just want to get the new RAM running at the 2400.

I suppose I have to go into the BIOS and find where to adjust individual individual RAM settings. CPU-Z shows the XMP-2400 as 11-13-13-31-44 with Command Rate of 1T. Not sure how to set that manually or why XMP preset would screw that up.

So I would be grateful for any advice (Step by step would really help).
Thanks in advance.

24GB? That's an odd #....................

1. Set XMP Profile
2. Set XMP Profile
3. Since you set the XMP profile, lol, add some System Agent voltage (.1V) and I/O voltage (.1V) and see if that helps.
4. They typically do... have you updated your motherboard's BIOS to the latest version? If not, do so.

That is fast ram for your CPU/system there bud. Not sure it will ever work right, honestly as the Memory controller I don't recall being able to run ram at those speeds...

Please post a picture of CPU-Z. The first tab, motherboard, memory, and SPD tabs please.

Hey. Thanks for the quick reply.
No I haven't upgraded the BIOS so I'll do that.
I've attached the screenshot of CPU-z
FWIW the manual indicates that the Rampage Extreme III supports DDR3-2400

We need the other screens... Mainboard, Memory, and SPD tabs........

Right. Here you go.

One thing... the board says it handles up to 2200MHz, not 2400Mhz............ but, they can usually handle more. The problem I think here will be you need to manually set the major timings and voltages since its not natively supported with your board.

Memory Feature
Tri-Channel, DDR3 2200(O.C.) MHz

The motherboard supports DDR3 memory that features data transfer rates of 2200(O.C.) / 2133(O.C.) / 2000(O.C.) / 1800(O.C.) / 1600(O.C.) / 1333 / 1066 MHz to meet the higher bandwidth requirements of the latest operation system, 3D graphics, multimedia, and Internet applications. The Triple-channel DDR3 architecture double the bandwidth of your system memory to boost system performance.

But I ask again.... HOW do you have 24GB of ram? 6x4GB????? The more sticks you have, the more stress is put on the Memory Controller. I would have went, since this is a triple channel platform, 3x6GB....

Yes 6x4. Why does that bother you so much? Overkill? OK maybe. Would it cause a problem somehow?

It can be a problem... Its likely overkill (as you didn't say you needed it...), but more so because of your goals here. More sticks increases stress on the IMC. You are trying to run 6 sticks at very high speeds... it just may not be in the cards with all of them.

OK. So what do you suggest? Remove two of the RAMS? Or try with all six? If it stresses the IMC what are the possible problems that can result? Instability? Failure? What? Thanks.

According to the part number, he's running three sets of these.
@jack d Your motherboard has had many BIOS updates since the version you're on, and several note increased memory compatibility. Here is the page you can download the newest BIOS from.
You may need to add some voltage to VTT to run all 24GB at >2200. As @EarthDog mentioned, that's going to be some decent stress on your IMC.

I suggest you:

1. Update the BIOS and try using XMP again...Not sure that platform supported XMP 1.3 though...
2. If that doesn't work, try setting your memory speed and main timings manually. Be sure to set the DRAM voltage to 1.65V and raise the VTT voltage .1V. Again, that is a lot of stress on the IMC.
3. If that doesn't work, try removing 3 sticks (make sure you look at the manual to see which slots they should be in with using 3) and repeat #1 and #2.

The uncore voltage is wrong, as always! XMP profiles are crap, and for different platforms, tbh they cannot work due to arch differences for each gen. Up the uncore to 1.35V at least.

@EarthDog it a X58... it has a tripple channel... what's the fuss about the size?

OK. I have to turn my attention to something else for a while but the next step is to update the BIOS. I already downloaded the latest version. Then the question will be is it worth risking the stress on the IMC or should I back off to 16 G of RAM and leave two slots empty? Thanks.

Thanks. Will update the BIOS in a while and then report back. You guys are super helpful. Very much appreciated.

Leave all 24GB in. Tweaking a few voltages for stability shouldn't be too tough with our help.

Well aware its X58 and triple channel.. I even said as much. I didn't say a word about size either??

What I am saying is that there is more stress on the IMC when you use more sticks of ram. This then causes one to raise the VTT voltage...


EDIT: GAH........ QPI/VTT on that platform.. SA and IO are for newer platforms and memory, LOL!

 

[Ferrum Master]

VTT/SA voltage...

Board makers are mixing the names... actually RAM VTT voltage is a Vram base voltage for differentiating 0/1 levels. The uncore, ring etc voltage is the north bridge voltage that we need here.

I guess it is all because from a translation from mandarin... or drugs .

@Ferrum Master - Drugs!

Thanks. Will update the BIOS in a while and then report back. You guys are super helpful. Very much appreciated.

Just a quick side note..... well, a preference anyway. I set voltages FIRST, then come back and change speeds, then timings. I have had issues just setting things all at once..... but maybe that was just me. LOL!

New RAM sticks... whatever what profile they have...

Set to MAX timings 14-14-14-40 or similar 1.65V VRAM, 1.35V Uncore. Go up from 1333 to 2400, if it boots, OK. Then decrease timings until it doesn't boot. Then starts the fine tuning process with stress testing... it takes a hell of a time, but at least it is bullet proof for older platforms for whom these ramsticks are NOT designed for.

Ok.
1. Updated BIOS and enabled XMP. Couldn't boot into WIndows
2. Am in BIOS now setting manually. Set dram freq to 2400. Set first four timings to 11 13 13 31. I'm not sure where to set VRAM or UNCore. Help appreciated.

Is VRAM set with the DRAM Bus Voltage?
Still can't find anything that looks like Uncore

 

[Jetster]

Try just 12Gb

Those will be in your voltages section, VRAM may be called VDIMM or DRAM Bus Voltage or something similar. Uncore is also known as VTT or VTT Core. Do not raise your VDIMM above 1.65V, and VTT @ 1.35V would probably be a decent starting point.

Ok Playing with the QPI/DRAM Core Voltage. When I got to 1.65 got a warning that according to INTEL that is too high??? Is that the wrong variable to set?
